[BREWMP] Add MarkStack fastMalloc implementation for platforms without VirtualAlloc or mmap.
https://bugs.webkit.org/show_bug.cgi?id=33582

Use fastMalloc and fastFree to implement MarkStack::allocateStack and
MarkStack::releaseStack for platforms without page level allocation.

  • runtime/MarkStack.h: (JSC::MarkStack::MarkStackArray::shrinkAllocation):
  • runtime/MarkStackNone.cpp: Added. (JSC::MarkStack::initializePagesize): (JSC::MarkStack::allocateStack): (JSC::MarkStack::releaseStack):
